A collaborative design between Karaku and illustrator 365CAT.ART, featuring a dreamy world where cats ride whales and drift through the ocean. The artwork transforms the whale into a giant “ship,” where cats relax, observe their surroundings, and enjoy a surreal marine journey. Rather than a simple animal print, the illustration tells a narrative—this storytelling-driven style is the core charm of the artist’s work. Swirling waves and glowing bubble-like particles fill the background, adding rhythm to the composition and creating a vivid underwater atmosphere.

The open-collar design enhances the relaxed aesthetic, making it ideal for casual summer styling. Natural wood-texture buttons further emphasize the laid-back, organic feel of the shirt.
